“Teen Mom” star Gary Shirley has been splashing cash on trips, toys and gadgets for himself, but his baby girl Leah has been left out, sources told RadarOnline.com exclusively.

“Little Leah hardly gets anything. Gary spends so much money on himself, but it’s rare that he’ll buy her anything,” said a source.

Following his split from his baby momma Amber Portwood, over the last few months Gary has been emptying his bank account — to the tune of about $24,000! — on a bachelor weekend in Vegas and furniture for his bachelor pad.

According to the source, Gary has also made even more thousands in media opportunities, which he’s already spent.
